Fire and Archery primaries, (nrg too, I think, if the KB doesn't mess it up), do better AoE dmg than elec/. Fire and Mental secondaries do better AoE dmg than /elec.
There's better builds for pure AoE madness. The strength of Elec/Elec (imho) is sapping mobs in 2 shots, and fast end recovery after nukes. You can stand toe-to-toe and blap pretty much anyone when they have no end left to fight you.
Stay Gold, Paragon. Stay Gold.
Nolite te bastardes carborundorum.
Be cautioned that complete sapping won't be possible until level 35 with Power Sink though.
Elec/Elec has proven to be more of a Jack-of-All kinda blaster for me. For true AOE as stated above, I'd go with Fire/Fire or Arch/MM
AR/MM
Maestro Mavius - Infinity
Capt. Biohazrd - PCSAR
Talsor Tech - Talsorian Guard

I have a Elec/Elec/Elec 50. Not the greatest aoe potential but makes up for it in your pbaoe potential. You will be fighting close to melee range most of the time to maximize your powers and endurance will never be a problem once your high lvl. Combine ranged and close attacks along with all the endurance drains means eazy breezy for your team. But dont forget that you will get one shotted if you get caugh slippn while you pbaoe.
You can't effectively end drain until power sink at lvl 35. By the time you reach the 40s you start running into a lot of factions where end drain or -recovery or both are resisted to varying degrees. Remember this when slotting end mod -- overkill is your friend.
Elec/elec, meh decent. Elec ^ 3, though is VERY sweet. Static discharge fills in a LOT of the aoe gap.
Elec ^ 3 to this day is still one of my favorite, and one of the best all around blasters in the game IMO.

Subject says it all. I started a blaster and went both Electricity and so far at my low level, as long as I am close, there is quite a bit of aoe coming from my elec. field. Does it get better later on?
